Buzz Feiten Retrofitter

1. Shelf Nut
Our exclusive Buzz Feiten Tuning System (BFTS) Shelf Nut moves the strings closer to the first fret according to our Patented Formula. This eliminates sharp notes at the first three frets.

Buzz Feiten Tuning System Shelf Nut

Top View : Each Shelf Nut is precision machined from high quality bone for superb tonal response. Our Lightning Bolt Logo is machined into the top of each Shelf Nut for authenticity.

Side View : The strings are moved closer to the first fret a precise distance based on the scale length, fret width and string gauge of your guitar. The slight overhang of our nut (the ‘Shelf’) does this without altering your guitar in any way. So it’s even fine for vintage guitars.
